Cement silo is a tank used by concrete mixing station to store cement and other powders. Generally, there are four silos in a concrete mixing station, which are used to store cement, additives (both raw materials for concrete production: fly ash and mineral powder) and other powders. When the production capacity of the mixing station is relatively large, the consumption of powder is very large. Sometimes the silo material level is low, which is likely to delay production and cause great losses to enterprises. Therefore, it is very necessary for the production of enterprises to know the height of materials accurately and know fairly well through some methods. The other is environmental pollution, which is also huge when the material explodes. The consequence is that the equipment needs to be repaired, and the on-site personnel are in danger, and the environmental protection department will also make corresponding penalties.
At present, the method to judge the material level of the silo is to install an anti-rotation material level meter at the upper and lower parts of the silo respectively. When there is no material in the silo, the high and low anti-rotation level meter rotates. When the filled material is higher than the low level, the low level anti-rotation material level meter is blocked by the material and cannot rotate, and the electrical signal changes, thus judging that the material is higher than the low level. Similarly, when the material reaches the high level, the high level anti-rotation level meter is blocked, and the electrical signal changes, thus judging that the material is higher than the high level.
At present, the detection method of silo material level can only be used as an alarm signal, that is, when the material is lower than the low material level, it is necessary to replenish the material; When the material level is higher than the high material level, stop feeding. However, when the height of the material is between the low position and the high position, the accurate material level cannot be detected by using the anti-rotation level meter.
In view of this, a technical problem to be solved by HXET material level measurement system is to provide a continuous monitoring device and method for the material level of concrete mixing station silo, which can effectively solve the above problems.
The invention relates to a material level detection device for a silo of a concrete mixing station, which comprises a material level measurement device of a heavy hammer material level meter arranged at the top of the silo; The material level measuring device is used to continuously measure the position of the material level in the silo, and the detecting device determines the material level in the silo through the physical contact position of the heavy hammer. The heavy hammer level gauge adapts to all kinds of harsh working conditions, especially the field conditions where dust and fly ash are extremely serious. The heavy hammer level gauge is superior to the radar level gauge!
